Fano-control of down-conversion in a nonlinear crystal via plasmonic–quantum emitter hybrid structures
Control of the nonlinear response of nanostructures via path interference effects, ie, Fano
resonances, has been studied extensively. In such studies, a frequency conversion process …

All-optical switching via coherent control of plasmon resonances
A novel ultrafast all-optical switching mechanism is demonstrated theoretically and
experimentally based on a plasmonic analog of the effect of\textit {Enhancement of Index of …

Negative superluminal velocity and violation of Kramers-Kronig relations in causal optical systems
ME Tasgin - Physical Review A, 2021 - APS
We investigate nonanalyticities (eg, zeros and poles) of refractive index n (ω) and group
index ng (ω) in different optical media. We first demonstrate that while a Lorentzian dielectric …
